' wwwrun fitted witlil a cover provided with a connection 2l, td whichtiexible tubing 2O is lconnected, said tubing leading to connectionsv22, communicating with the small receptacle 13, arranged Within themoisture pan ll, above described. rlhe exit of each of these lattermentioned connections 22, is beneath the surface of the Water containedin the receptacles 13, to form a seal and'retard and vash the flow ofoxygen from the generator 1S.1 A small vertically arranged exit tube 23,is fitted in the top of each of the receptacles 13, and projectsupwardly through large tubes 24, formed with the wire mesh bottom oi'the earth pan Ll. This arrangement will permit the oxygen to tiow upwardinto the incubator proper, and nourish the embryo or live chickstherein. As the embryo grow they give ott an increasing' amountot usedup air. This is poisonous, being` laden with the Waste products of theirown developing bodies, hence the use of oxygen and the destruction otsaid poison-laden air, which latter is accomplished by the use of theabove described chemical disinfectant.

'The oxygen generator is supported on a bracket 26, attached beneath thedrawer 7, but may be arranged in any suitable position, and the conduitsQ0, leading therefrom fitted with regulatingvalve 24, if it is sodesired. It will 4be noticed that the contents of thfe drawer 7, may beremoved, cleansed and replaced Without undue labor, as the several pans,etc., are not permanently lixedbutmerely placed in loose compact form.

rlhe operation of the above incubator does not dittermaterially from thebest form now in use, but with the additional new i'eatures hereindescribed, better results, sucn as a. greater yield, or percentageolf-chicks are pro-cured, as Well a healthy strong brood of chicks, theresult ot hygienic and natural environments.

Many slight modifications may be made in the construction ot theldetails Without departing from the. spirit of the invention.

I claim.

l. An incubator comprising a compartment, a means of supplying heatthereto and moisture therein, and suitably arranged egg trays, incombination with a sliding drawer,

having` arranged therein a moisture pan, an

learth pan with perforated bottom arranged above said moisture pan, ano'pen receptacle for disinfecting and purifying material, an oxygengeneator having ducts leading to receptacles arranged in said drawer,and having exit tubes trom said receptacles discharging above the levelot' said earth pan.-
